ndak. semua port USB (baik 1.1 maupun 2.0) punya spesifikasi power yang
sama.

=== Tx, koreksinya, Pak Ryo. Sekarang saya jadi ingat, terutama dari link
http://en.wikipedia.org/wiki/USB#Power. Dulu pernah pakai MacOS, terus hanya
mencolokan satu USB saja, hdd eksternal 2,5" yang dipakai "ogah" jalan
karena kurang tenaga.

For portable devices where external power is not available, but not
more than 1 A is required at 5 V, devices may have connectors to allow
the use of two USB cables, doubling available power but reducing the
number of USB ports available to other devices.

=== doubling available power but reducing the number of USB ports available
to other devices. - sudah pasti jadi tekor satu port. ^_^
